Fallbi is a young Nimbi living in The Overthere. Her name is a pun on the season of Fall, and her boyfriend, Novbi, may be named after the last month of Fall in the Northern Hemisphere. When Mario first meets Fallbi in Super Paper Mario, her boyfriend has been completely frozen, but with Bowser's help, they are reunited. Fallbi loves eating candy.
